ffmpeg problem - CalledProcessError: Command '['ffmpeg', '-version']' returned non-zero exit status -6 #141

Hi guys, I am having problem executing the code Solution for Deep Q Learning. I have installed the ffmpeg package, which was missed but I got this problem now and I have no idea how to solve it.

Anyone has already encountered?

This is my error trace:

Had this on OSX and fixed it by upgrading my ffmpeg with brew $ brew upgrade ffmpeg
